Safety standards require operator
presence controls to minimize the risk of
injury. Your unit is equipped with such
controls. Do not attempt to defeat the
function of the operator presence controls
under any circumstances.
TRAINING:
• Read this operator's manual carefully,
Become familiar with the controls and
know how to operate your mower
properly. Learn how to quickly stop
mower.
• Do not allow children to use your
mower. Never allow adults to use
mower without proper instructions.
• Keep the area of operation clear of all
persons, especially small children and
pets.
• Use mower only as the manufacturer
intended and as described in this
manual.
• Do not operate mower if it has been
dropped or damaged in any manner.
Always have damage repaired before
using your mower.
• Do not use accessory attachments that
are not recommended by the manufac-
turer. Use of such attachments may be
hazardous.
• The blade turns when the engine is
running.
PREPARATION:
• Always thoroughly check the area to be
mowed and clear it of all stones, sticks,
wires, bones, and other foreign objects.
These objects will be thrown by the
blade and can cause severe injury.
• Always wear safety glasses or eye
shields when starting and while using
your mower.
• Dress properly. Do not operate mower
when barefoot or wearing open sandals.
Wear only solid shoes with good traction
when mowing.

• Check fuel tank before starting engine.
Do not fill gas tank indoors, when the
engine is running or when the engine is
hot. Allow the engine to cool for several
minutes before filling the gas tank. Clean
off any spilled gasoline before starting
the engine.
• Always make wheel height adjustments
before starting your mower. Never
attempt to do this while the engine is
running.
• Mow only in daylight or good artificial
light.
OPERATION:
• Keep your eyes and mind on your
mower and the area being cut. Do not let
other interests distract you.
• Do not mow wet or slippery grass. Never
run while operating your mower. Always
be sure of your footing -- keep a firm
hold on the handles and walk.
• Do not put hands or feet near or under
rotating parts. Keep clear of the dis-
charge opening at all times.

• Before cleaning, inspecting, or repairing
your mower, stop the engine and make
absolutely sure the blade and all moving
parts have stopped. Then disconnect the
spark plug wire and keep it away from
the spark plug to prevent accidental
starting.
• Do not continue to run your mower if you
hit a foreign object. Follow the procedure
outlined above, then repair any damage
before restarting and operating you
mower.
• Do not change the governor settings or
overspeed the engine. Engine damage
or personal injury may result.

abnormally. Excessive vibration is an
indication of damage; stop the engine,
safely check for the cause of vibration
and repair as required.
• Do not run the engine indoors. Exhaust
fumes are dangerous.

• Your lawn mower is equipped with an
operator presence control bar which
requires the operator to be positioned
behind the lawn mower handle to start and
operate the lawn mower.

• Raise wheels for low cutand lower wheels
for high cut.
• Adjust cutting height to suityour require-
ments. Medium position is best for most
lawns.
• To change cutting height, squeeze adjuster
lever toward wheel. Move wheel up or
down to suit your requirements. Be sure all
wheels are inthe same setting.
NOTE: Adjuster is properly positioned
when plate tab inserts into hole in lever.
Also, 9-position adjusters (if so equipped)
allow lever to be positioned between the

BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped without oil
in the engine.
• Be sure mower is level and area
around oil fill is clean.
• Remove engine oil cap and fill to the
full line on the dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engine holds 20 ozs. of oil. For type
and grade of oil to use, see "ENGINE"
in Maintenance section of this manual.
• Pour oil slowly. Do not over fill.
• Check oil level before each use. Add
oil if needed. Fill to full line on
dipstick.
• To read proper level, tighten engine oil
cap each time.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may
need to change the oil more often
under dusty, dirty conditions.
ADD GASOLINE
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
AWARNING: Experience indicates that
alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructions
for additional information. Never use
engine or carburetor cleaner products in
the fuel tank or permanent damage may
occur.
AI_CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

TO START ENGINE
• To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
• Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
• To stop engine, release operator
presence control bar.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
flooding and engine will not start. If you
do flood engine, wait a few minutes
before attempting to start and do not
repeat priming steps.

MOWING TIPS
• Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing
effort and to keep from overloading the
engine and leaving clumps of grass
clippings. It may also be necessary to
reduce ground speed and/or run the
lawn mower over the area a second
time.
• For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
• For better grass bagging and most
cutting conditions, the engine speed
should be set in the fast position.
• When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed
(pushing speed) and/or run the lawn
mower over the area a second time.
• If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
overlap to collect the clippings on the
next pass.
• Pores in cloth grass catchers can
become filled with dirt and dust with use
and catchers will collect less grass. To
prevent this, regularly hose catcher off
with water and let dry before using.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and
extend engine life.
MULCHING MOWING TIPS
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. See "Cleaning" in
Maintenance section of this manual.
• The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into
the grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn.
Always mulch with your highest engine
(blade) speed as this will provide the
best recutting action of the blades.
• Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action.
The best time to mow your lawn is the
early afternoon. At this time the grass
has dried and the newly cut area will
not be exposed to the direct sun.
• For best results, adjust the lawn
mower cutting height so that the lawn
mower cuts off only the top one-third of
the grass blades. If the lawn is
overgrown it will be necessary to raise
the height of cut to reduce pushing
effort and to keep from overloading the
engine and leaving clumps of mulched
grass. For extremely heavy mulching,
reduce your width of cut by overlap-
ping previously cut path and mow
slowly.
• Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings. When doing a
second cut, mow across or perpen-
dicular to the first cut path.
• Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week. This will help prevent matting
and graining of the lawn.
